The EncryptStick with Private Browser is new from ENC Security and works with Windows or Mac. Get it for $40 at Encryptstick.com.

It encrypts your files and your whole web browsing experience. Install it on a flash drive and browse the web using that drive with any computer. This is very handy for online banking and other private activities. No record of your actions remain on the computer when you remove the flash drive. A free version of this software is available at the company’s web site but does not include the private web browser.
